Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2012 Chevrolet Colorado Owner Comments

problem #4

Nov 262014

Colorado 4WD 5-cyl

  • 39,138 miles


ABS brakes and stabilitrac lights on dash upon starting, taken to dealer on 11/27/2014, miles 39138, failed again 12/19/2014, miles 39780, and 12/31/2014 for same problem. Truck is still at dealer as of 01/16/2015. After first failure braking was not right, and the truck needs a part that can not seem to be found to date. I believe this truck is unsafe to drive due to the brake issue, and will not keep the truck upon return, but I am fearful that it will be sold to another consumer, and it will be involved in a tragedy.

The "service stability system" warning light comes on and stays on until the vehicle is shut down. It does that repeatedly. The Chevrolet dealer, jim cook Chevrolet in marion, nc, says they cannot duplicate the light or detect a code and that there is nothing wrong with the vehicle and the light is meaningless and I should disregard it. The user manual states that if this light comes on the vehicle should be immediately parked and taken to the dealer for repairs. This has happened repeatedly for the year I have had the truck. It has been in the shop numerous times. On one occasion, may of 2014, the shop tech at jim cook did see the light come on and he changed the "yaw senor". it did not fix the problem. Now the dealer service manager denies that anyone ever saw the light come on at their shop. Also, the jim cook manager says that all records they have of serving this truck were sent to GM on orders of the regional GM office and they no longer have any records of serving the truck. The light still comes on and I am afraid to drive the vehicle. Chevrolet customer service opened then closed a case on the issue and now tells me I am simply a dissatisfied owner and they will not longer service the truck or deal with me. I even asked the dealer if they would take the truck back in trade for another vehicle, as I really need a reliable truck. They told me that they would not take the truck in trade or in any other manner and I needed to take the matter up with Chevrolet.

At first, truck showed tps alarm, then stability alarm, next it had the headlights cut out on the highway at night @ 70 mph for 15-30 seconds. It has shown these problems separately and simultaneously at different times. Finally it manifested a new symptom I would intermittently not crank the engine over even though the battery was at full charge. After repeated trips to the dealer(they said they could not reproduce the problem) with no effect or improvement, a call to Chevrolet netted a case number #71-1257538002. As a result of this call( I feel) work was restarted on the vehicle. As of today 12/26/13 the Chevrolet dealer has now changed the ignition switch. We shall see.

At approximately 350 miles on the truck odometer, the dashboard warning module on my new 2012 Chevrolet Colorado pickup truck illuminated with "service stab sys". the warning light remained on until I parked the truck. I took the truck to the dealership service center. The service representative at the dealer told me to ignore the warning light. The technician could not find a fault code stored that reflected a stability problem. He told me that no such warning could have illuminated or it would be in the memory of the vehicle??S computer. This warning message: " service stab sys" and the traction warning light now come on repeatedly. In July 2012, while driving at 65 mph on I-40, the same warning illuminated. This was followed immediately by a violent shudder in the steering system and what felt like uneven application of the front brakes for fractions of a second. I pulled over and called onstar who ran a system check. Onstar could see the stability system warning was on but no fault code was detected. I took the truck back to the dealership. They told me that there was no fault recorded in the vehicle memory and they could find nothing wrong with the truck and were unable to duplicate the problem. They told me that there was no system or function in the truck or the stability system that could make the truck shudder as I described or that could independently apply braking. This has happened repeatedly, with the shudder also re-occurring. Chevrolet and the dealer tell me there is no prior history of problems with the stability system in Colorado pickups. Such shuddering in the steering at highway speed cannot be a safe condition. On one occasion onstar detected a code of C-197. The truck is again at the dealership service center who state that they can find nothing wrong with the stability system in the truck.
